Definitions
- the present invention relates to the harvesting of blood vessels and, more particularly, to a method and apparatus for dissection and removal of sections of blood vessels.
- the harvesting of blood vessels also includes the use of insufflators in order to create an open area around the vessel being dissected and harvested.
- the insufflators are attached to supplies of air or CO 2 that are connected to external sources in the operating room.
- the currently available insufflators are typically intended for use in general and gynecological endoscopic surgeries, and have historically performed safely when used as intended. Such insufflators are commonly utilized in both day surgery and hospital operating rooms. Many types of endoscopic surgical procedures that include the use of insufflators typically require several liters of CO 2 to inflate and maintain the area surrounding the surgical site.
- the integrally adjustable insufflation device can include a one-way valve positioned at a distal end of the sheath.
- the one-way fluid control valve allows the insufflation fluid to exit from the integrally adjustable insufflation device, but prevents debris from entering the integrally adjustable insufflation device.
- the integral fluid-regulating endoscopic device 10 also allows the clinician to quickly adjust, and thereby regulate, the fluid pressure and/or flow rates from within the sterile field.
- the insufflation gas is discharged from the distal end 18 into the subcutaneous area in the body.
- the sheath 12 can include one or more discharge ports or holes 19 that are in fluid communication with the inner space 14 .
- the insufflation gas escaping from the distal end 18 and/or ports 19 enters the subcutaneous area around the vessel and keeps the surrounding tissue away from the endoscopic device 10 .
- the integrally adjustable insufflation device 30 prevents any excessively high pressure and excessively fast flow rates of insufflation gas from exiting the endoscopic device 10 .
- the integrally adjustable insufflation device 30 ensures that the pressure and/or flow rates of gas entering (and ultimately exiting) the inner space 14 of the endoscopic device 10 are adequate, but not excessive.
- the integrally adjustable insufflation device 30 can provide a “step-down” of the pressure and/or the amount of insufflation gas exiting from the inner space 14 , while simultaneously allowing a substantially continuous flow of the insufflation gas into the subcutaneous area.
- the one-way fluid control valve 36 allows the insufflation gas to pass from the supply line 32 , but prevents debris from entering the supply line 32 .
- the integrally adjustable insufflation device 30 includes one or more fluid control mechanisms 38 that configured to regulate at least one of a pressure and flow rate of the insufflation gas being supplied to the subcutaneous area.
- at least one fluid control mechanism is designated as an internal fluid control mechanism 38 and at least one other fluid control mechanism is designated as an external fluid control mechanism 44 , as further described below.
- the internal fluid control mechanism 38 is operatively connected to the supply line 32 .
- the internal fluid control mechanism 38 is configured to control the pressure and/or the flow rates of the insufflation gas being discharged from the supply line 32 via the one-way control valve 36 .
- the internal fluid control mechanism 38 can be either a one-way valve or a pressure relief type regulator that acts as a “high-pressure/flow step-down” mechanism.
- the internal fluid control mechanism 38 can include a precision pressure/flow rate gauging, or setting, mechanism. It is to be understood that other suitable mechanisms can be used that allow the clinician to also infinitely vary the pressure and/or flow rates of the insufflation gas being delivered through the supply line 32 to the subcutaneous area surrounding the vessel.
